Canis Lupus Familiaris, the
scientific name of a dog. Dogs are animals and have lived since the Late Pleistocene(unofficial time period and also known as Upper Pleistocene). So basically nobody knows exactly when the first dogs came into
existence. However we do know that dogs(Canis Lupus Familiaris) coexisted with humans. The first dog that was
domesticated was way after that, in northern Siberia(now freezing cold Russia) 23000 years ago.
